Title: Low-range radio transmission telephone installation comprising sets each usable by several persons simultaneously
IPC: H04M1/725
Filed: 1986-02-19
Abstract: The installation comprises sets 10 located in public places and rendered virtually invulnerable since they contain no fragile or vulnerable element: no handset, no cord and no money. Each user carries with him a very small-sized handset 1, including a keypad 102, an earpiece 103 and a microphone 104. It contains a radio transceiver 100 and an antenna 101. To telephone from the portable handset 1, the user stands at a distance of a few metres from an arbitrary set 10, switches on his transmitter 100, dials for example an account number and a code number on the keypad 102 and is thus enabled to use the set 10 which includes a radio transceiver 201 and an antenna 200 as well as a recognition unit 203 and a modem 205 connected to everyday telephone lines. The user can then dial the call number of the party and speak to him. Several users can use the same set 10 simultaneously, the latter having either several radio transceivers or just one equipped with several channels tuned to that of each handset.

Title: Reinforced sanitary ware and its manufacturing process
Inventor: WOOD RICHARD
IPC: B29C44/34
Filed: 1986-03-21
Abstract: Process for manufacturing an item of sanitary ware from a profiled thermoplastic shell and process a curable rear-layer composition preferably made from polyurethane foam, in which item a metal structure is placed in the curable rear layer, so as to constitute a heat absorber for the heat generated during the curing and possibly to rigidify the article, the curing taking place in a closed mould. The process prevents deformation of the thermoplastic shell, which is produced when curable compositions are used having exothermic curing reactions, in particular when the thermoplastic shell is formed from a sheet less than 5 mm thick.

Title: Direct deposition of metal patterns for use in integrated circuit devices
Inventor: LIU YUNG SHENG
IPC: H01L21/768
Filed: 1986-11-17
Abstract: For direct deposition of patterns in refractory metal on a substrate 10, sources of radiating thermal energy 25 are used. Patterns in metallic tungsten are deposited selectively on silicon surfaces by relying on a vapour phase reaction brought about by a transient radiation source. Regular patterns in refractory metal are produced with a better resolution by directing the radiating energy by means of a mask 20 so as to bring about localised heating and cause a localised reduction of a refractory metallic gas by the silicon, for example.

Patent FR-2617927-A1 (FR)
Inventor: TOBIASZ ANDRE
IPC: F16D65/22
Filed: 1987-07-08
Abstract: The hydraulic brake actuating device comprises a cylinder body (1) with an inlet (2) for the pressurized fluid and first and second pistons (7 and 4) for actuating brake shoes. The cylinder body (1) also includes a third piston (3) in which the first piston (7) slides telescopically in a fluid-tight manner. The first and third pistons (3 and 7) present two active faces (S1 being one) bounding a working chamber formed by first and second compartments (14 and 15) for the pressurized fluid. Means is provided to vary the active faces of the pistons during the rise in the hydraulic pressure in the cylinder. The means comprises a valve arrangement (17) connected to the third piston (3) and arranged to close off a passage (16) to isolate the two active faces of the pistons the one from the other at a predetermined hydraulic pressure in the working chamber by isolating the first compartment (14) from the second compartment (15). Thus further increase in hydraulic pressure at the inlet (2) only serves to raise the pressure in the first compartment (14) which only allows the increase to be applied to the active face (S1) on the third piston (3). Therefore the braking effort increases at a reduced rate because active face (S1) is of lesser area than the sum of the two said active faces.

Title: Electrically programmable memory with programming control circuit and corresponding method
Inventor: DEVIN JEAN
IPC: G11C16/28
Filed: 1988-04-26
Abstract: The invention relates to electrically programmable memories, and especially memories known by the abbreviations "EPROM", "EEPROM", "FLASH-EE-PROM". In order to take into account the loss of charge from the floating-gate transistors over time, it is proposed to read the memories while comparing the output current from the cells not only with a reference value IR defining the boundary between programmed cells and non-programmed cells, but also with a second reference value IR1. If the output current is between these two values (in other words if it is too close to IR) a complementary programming of the cell is carried out.
